Diaphragms

Diaphragms

Contraceptive caps and diaphragms are barrier methods of birth control that are slightly different but work in similar ways. The only type of this contraception available currently is the Caya diaphragm.

A diaphragm is a shallow latex dome that fits inside a woman’s vagina. It works by covering the cervix and surrounding area and preventing sperm from passing into the uterus (womb) and fertilising the egg. It is usually used with spermicide gel that kills sperm on contact.

Spermicidal gels are no longer available and the Caya diaphragm is used with Cyagel instead.

How effective are diaphragms?

How effective are diaphragms?

Most women can use a diaphragm however, because they work by covering the cervix, anything that prevents them from fitting properly will make them less effective. A diaphragm may not be suitable for you if:

  • you have an unusual shaped cervix
  • you can’t reach your cervix (this feels like a hard bump inside your vagina)
  • you have weak vaginal muscles (perhaps from giving birth)
  • you have a vaginal infection

When you have  a consultation at a Devon Sexual Health clinic you can chat with your doctor or nurse and they will be able to give you advice about the best form of contraception for you.

You can get a Caya diaphragm from your nearest Devon Sexual Health clinic. You can book an appointment with us via the telephone, or online by registering for a Personal Health Record (PHR) to discuss your contraceptive needs or sexual health with our specialist team. You may also be able to purchase diaphragms online and some GPs are also able to advise about Caya use.

Are there any side effects?

Are there any side effects?

There are not usually any side effects associated with the diaphragm as a form of contraception. It is really important to remember that the diaphragm cannot prevent sexually transmitted infections (STIs).

Caya diaphragms do not have to be fitted and there is only one size which is expected to fit most people. If you are unsure whether your Caya fits you adequately, we can happily advise you about this.
